Sample WAEC Mathematics Questions and Answers 2026

Question 1: Number and Numeration

Question: Express 0.025 as a fraction in its simplest form.
Answer:
0.025 = 25/1000 = 1/40

Question 2: Algebra

Question: Simplify: 3x + 2y – (x – 4y).
Answer:
= 3x + 2y – x + 4y
= 2x + 6y

Question 3: Geometry

Question: The sum of the angles of a triangle is?
Answer:
180°

Question 4: Trigonometry

Question: If sin θ = 3/5, find cos θ.
Answer:
Since sin²θ + cos²θ = 1,
cos²θ = 1 – (3/5)² = 1 – 9/25 = 16/25
∴ cos θ = 4/5

Question 5: Mensuration

Question: Find the area of a circle of radius 7 cm.
Answer:
Area = πr² = 22/7 × 7 × 7 = 154 cm²

Question 6: Statistics

Question: Find the mean of these numbers: 5, 10, 15, 20, 25.
Answer:
Mean = (5 + 10 + 15 + 20 + 25) / 5 = 75 / 5 = 15

Question 7: Consumer Arithmetic

Question: A fan costs ₦8,000. If VAT is 7.5%, find the total cost.
Answer:
VAT = 7.5% × ₦8,000 = ₦600
Total cost = ₦8,000 + ₦600 = ₦8,600

Question 8: Probability

Question: A box contains 4 red and 6 blue balls. What is the probability of picking a red ball?
Answer:
P(Red) = 4 / (4 + 6) = 0.4

Question 9: Linear Equation

Question: Solve for x: 3x + 5 = 20.
Answer:
3x = 15
x = 5

Question 10: Set Theory

Question: If A = {1, 2, 3, 4}, B = {3, 4, 5, 6}, find A ∩ B.
Answer:
A ∩ B = {3, 4}

Important WAEC Mathematics Formulas to Remember

1. Area of a rectangle = length × breadth

2. Area of a triangle = ½ × base × height

3. Area of a circle = πr²

4. Circumference of a circle = 2πr

5. Volume of a cylinder = πr²h

6. Pythagoras theorem = a² + b² = c²

7. Simple interest = (P × R × T) / 100

8. Quadratic formula = (-b ± √(b² – 4ac)) / 2a

9. Mean = Sum of values / Number of values

10. Probability = Number of favorable outcomes / Total outcomes

These formulas appear in most WAEC questions every year, so you should memorize and practice them regularly.
